Inventor: SAMAIN DANIEL
IPC: D06M13/188
Filed: 1998-08-14
Granted: 2007-10-16
Abstract: The invention concerns a method for treating a solid material whereof the chemical structure defines the reactive protogenous hydrophilic functions accessible to gases by applying at least a gas stream (3) on at least a micro-dispersion (5) of at least a grafting reagent RX produced on the solid material, R being a hydrophobic group, X being selected such that HX is volatile in normal conditions, R and X being selected such that the reaction of RX on the hydrophilic functions produces the covalent grafting of the hydrophobic groups R with formation of the compound HX, the reaction capable of being carried out in heterogeneous solid gas medium on all the reactive hydrophilic functions accessible to gases and only thereon. The invention also concerns the resulting hydrophobic solid material, and is useful for obtaining natural or artificial fibrous or mineral structures impermeable to water and to aqueous solutions and/or absorbing fats.

Abstract: In order to predictively time stamp isochronous data packets transmitted over an IEEE 1394-1995 serial bus network, an application, which is to send a stream of isochronous data packets to a receiving node, first transmits a number of dummy frames each consisting of a number of packets. Preferably, these isochronous data packets make up frames of video data. From these dummy packets, the application obtains the time stamp values within the common isochronous packet (CIP) header of each packet. Using these obtained time stamp values, the application calculates a presentation time value for each data frame to be transmitted. The obtained time stamp value from a transmitted video frame is used to calculate the presentation time for a video frame which is a number of frames ahead within the transmit queue. Once the presentation time value for a frame is calculated, that value is then inserted by the application into the CIP header for the first packet within that frame and the frame is sent to the transmit queue for transmission to the receiving node over the IEEE 1394-1995 serial bus network.

Abstract: A heat-transfer label assembly. In one embodiment, the assembly comprises a carrier, the carrier comprising a paper substrate overcoated with a layer of polyethylene. The polyethylene layer is overcoated with a skim coat of wax. One or more heat-transfer labels are printed onto the skim coat and are spaced apart from one another, each label comprising a protective lacquer layer printed onto the skim coat, an ink design printed onto the protective lacquer layer, and a heat activatable adhesive layer printed over the ink design, any exposed areas of the protective lacquer layer and a surrounding area of the skim coat. The periphery of the skim coat extends beyond the periphery of the label and is, therefore, uncovered by the label. The assembly further comprises a mask deposited over the uncovered areas of the skim coat, the mask adhering to the polyethylene layer during label--transfer and preventing transfer onto an article of the previously uncovered areas of the skim coat together with the label.

Title: Treatment of oxidable gas generated from waste at a dumping area
Inventor: ETTALA MATTI
IPC: B01D53/85
Filed: 2000-09-01
Granted: 2009-01-20
Abstract: The invention relates to the method for treating oxidable gas generated from waste at a dumping area and to the structure of the dumping area constructed for t he method. As the dumping area has been filled up, the organic waste layer (1) is cov-ered with a sealing layer (2) preventing the absorption of water and wit h an overly-ing layer, typically a drying layer (3) and a surface layer (4). In oxygen-free condi-tions in the waste layer (1), oxidable gas, mainly methane, is generated, which is, according to the invention, directed in a self-operated manner through the penetra-tion aperture (10) formed to the sealing layer and made to spread in the lateral direc-tion with the help of one or several flow controllers so that the gas ends in the sur-face layer (4), in which it becomes biologically oxidised because of the effect of microbes. The penetration aperture may be formed of the well (10) provided with the cover (11), and the gas flow controllers may be perforated pipes (12) extending radially from the side of the well. The oxidation of gas may be intensified by direct-ing air and/or moisture from the piping (15) to the surface layer (4) .

Title: Imaging and analyzing parameters of small moving objects such as cells
Inventor: ORTYN WILLIAM E
IPC: G02B27/00
Filed: 2000-10-12
Granted: 2005-04-26
Abstract: Light (30) from an object (24) such as a cell moving through an imaging system (20) is collected and dispersed so that it can be imaged onto a time delay and integration (TDI) detector (44).  The light (30) can be emitted from a luminous object (24) or can be light from a light source that has been scattered by the object or can be a fluorescent emission by one or more FISH probes, frequently used to detect substances within cells. Further, light that is absorbed or reflected by the object can also be used to produce images for determining specific characteristics of the object. The movement of the object matches the rate at which a signal is read from the TDI detector. Multiple objects passing through the imaging system (20) can be imaged, producing both scatter images and spectrally dispersed images at different locations on one or more TDI  detectors (44).

Abstract: The secure electronic distribution of research documents over the world wide web to investors. A repository server (2) receives research documents from contributors (14, 16, 18, 20, 22). Also received are corresponding document profiles with information relating to each research document including authorization information specifying who is permitted to access each research document. The repository server (2) includes a first database (11) for structured query searches and a second database (13) for full text searches. The web server (4) receives requests from investors for research documents that satisfy a query. The web server (4) determines whether the first database (11) or the second database (13) should be searched based upon the type of query. The repository server (2) transmits to the web server (4) a list of research documents that satisfy the query and which the investor is authorized to access according to the authorization information. The web server (4) formats the list of documents according to a template form. Optionally, queries can be optimized.

Abstract: L'invention concerne un capteur utilisé dans des situations de surveillance d'un patient, le niveau de changement de position dudit patient étant suivi afin de déterminer si ce patient présente ou non une activité suffisante pour éviter un déplacement planifié dans une nouvelle position. Le dispositif fonctionne sensiblement de façon à capter l'intervalle de temps écoulé depuis le dernier changement de position assise ou allongée du patient. Si ce patient n'a pas changé de position pendant un intervalle de temps prédéterminé, il est préférable d'informer le personnel soignant qu'il est temps de changer manuellement la position dudit patient. Si le patient a changé de position dans un intervalle de temps spécifié, le dispositif enregistre ce fait et informe l'infirmière ou une autre personne soignante que le patient n'a pas besoin de changer de position avant le prochain changement de position planifié, ce qui évite dans certains cas de le réveiller. Dans les deux cas, l'invention fonctionne de façon à réduire le risque de développement d'escarres de décubitus par le patient, par information du déplacement manuel du patient aussi souvent que le médecin le requiert, mais pas plus que nécessaire.
